Automata

At last, the infamous unit at the end of tech, automata. The self oparating machine that only requires a turn of the handle. My fist idea was going to be a herd of bulls that requireda catipilla mechanism inside the machine. Basically the whole class was intending to have the same idea, so I decided to do something else. I then came up with the idea of a bird. There would be one central piston at the top, being forced upward by an egg-shaped gear on a horizontal axel. This would be topped by a bird that elevates repeatingly alonsgside the egg shaped gear. The wings would be held in place to create a flying illusion. I will talk more in depth about the creation process tommorow.

Flashlights

Behold, a new project revealed today. Flashlights. Apperently, you are supposed to save these Thaiwanese kids who are trapped in a cave with falshlights made of PVC pipe. My brain was brewing with a soup of ideas, yet half of them were killed when our teacher said they needed to fit in a specific small area. When he also said that they need to be waterproof, all of my my original ideas were absolutly slaughtered. There was only one little spark left in my head;a small, wrist held flashlight. After much vigourus diagramming, I was going to put it up to the test. The first second that I showed my hard work to my teacher, he rejected it and said that it didn’t fit in the box. Arghh! I will report about the rest tomorrow.

Switches 2

Now it’s time to talk about the third switch. First of all, I had this interesting idea. There would be a piece of cardboard with a line cut inside it with a second flap of cardboard inside this line. You would have to pull back to create contact between the smaller flap and a wall of aluminum at the back, closing the circuit. There would also be a rubber band at the front creating resistance, so you did not have to pull the flap forward again when you desired to open the switch. Here is where it starts going sideways. The whole that I cut in the large piece of cardboard was not long enough for the flap to fully touch the back wall, so then I thought the back wall could rotate to the cardboard as the flap touches the bottom. I still shun myself for being such an idiot. The flap still can’t  touch the bottom because it was too small & short. Eventually, the final idea that came out of me was to use this new rotating lever to press down on the flap. People asked why there was a long hole in the cardboard and it was painful to lie to them. I hope that never happens again.

Switches

Amazing! I finished every single one of my switches. Surprisingly, only one came out to match my vivid thoughts. I deeloped my first Idea over a course of a few days. There would be a wheel that turned a central axis that in turn turned a flap to come in contact with some aluminum that finally would activate the battery. After a few troubles with hot glue (ouch), the switch finally turned into what I dreamed it to be! Okay, here is when it gets wierd. I planned for my second switch to invovle a lever pushing another lever down to a bed of tinfoil, closing the switch. Here is a picture of this:

It actually became the reverse of what I planned it to become. Instead of appying force to the back lever, the switch was repurposed to push the front lever in opposite motion. It was not what I intended, but it worked. The last switch would take a lot of explaining, so I will do that in another post.

Soldering

At long last, we are learning about soldering. Solddering= Basically hot glue with molten metal instead. You can use tis technique to glue different parts of circuits together while still being conductive. When constructing a circuit, using hot glue will stop the flow of electrons through the circuit. When you do this, the circuit is no longer closed, so it will not work. On Monday, we will actually start using this incredible machine. I have this great idea for a switch that I can’t wait to make a reality.

Circuits

Today was circuit day! We started learning about batteries, multimeters and the flow of electrons. First of all, batteries contain two cores. The inner core and the outer core. the inner core contains zinc with added electrons, while the outer core contains positively charged copper, or copper with removed electrons. When you connect the two ends with a conductive material, the electrons from the zinc start flowing to the copper, creating electricity. You should never connect the top end and the bottom end, for the electrons flow out of control. This can potentially spark and ignite. We learned all of this today! Tomorrow, we will finally be creating these circuits!

Atoms

Atoms are completely consist of three particles. Protons, Electrons, and Neutrons. Particles of the same charge repel each other. When they are of opposite charges, they stick to each other. Protons are positively charged, and electrons are negatively charged. Neutrons are neutral. If your insert a neutron between two particles of the same charge, they do not repel each other. That was our lesson today in tech, and it was interesting. Tomorrow we are learning more about attractions and electrons. Looking forward to it.

Technology Breakout EDU

Tech, and also more important, Middle School! We have just transitioned to the 4th quarter of my first year at middle school. In tech yeasterday, we tried to solve the puzzle that our teacher presented before us. It involved unlocking one of two boxes with multiple locks on them. Inside was the solution.

 

We were split into two groups, and we surprisingly solved the puzzle. Within groups, I noticed most of the time that everyone gets into a heated debate about who gets to do what. But, in this scenario, it worked out fine. It would have been less efficient to work in any smaller groups. We could spread out and surch an area very quickly. That5 is basically what I learned yesterday, and I hope we do more!

Capstone Presentation and Reflection

When I woke up on Tuesday, you can’t really say that I was nervous. I was around nervous x 15 x 10 to the 38th power. I was like this because way in the morning before the capstone presentation, there was this ceremony called the moving up ceremony. This was when we sang in front of all the parents and showed that we were “moving up to middle school”. I was playing piano as the precessional and I was playing a really hard piece that I only learned two days ago and it was a bit shaky. This combined with the factor that I was presenting an unprepared presentation. Then I figured out that “Oh wow, I am presenting first as well.” Let’s just say that It was not a great scenario. I was thinking that all this work and progress is going to be broken down into some twitching words and uncoordinated slides. Capstone has been really fun. experience for me and I hope we get to do something like this again in middle school. I learned a very crucial thing in this project: You should never slack off if you think a project is long term, for it is not. You had to every da to make the project your best, but I skipped most days, and I payed at the end for working the hardest I ever worked at the end. I vow that I shall never repeat this behavior in a project ever again.

Half of my nervousness retreated when I played the peice well with only one mistake. I recieved a wooping crowd and I was enormously relieved. There was still a huge wall ahead of me on the road to relaxation. This was my Capstone Presentation. I had not memorized my script, but my dad said it was okay as long as you don’t stare at your note cards the whole time. I strategy I used while presenting my presentation was that l Iooked at the back wall instead of the people. Unfortunatly, my presentation was 11 min long. It was wierd since it felt like it was done in 2 seconds. Even stranger, my teacher told me that I did agreat job. Turns out, I did do a great job since many people including my parents siad the same thing. My parents are honest, so when they said I did good, I believe them. Hope we get to do something like this in middle school, but for now, summer here we come.

Answering Main Inquiry Question Part 2

I finally know the second part of my main question! Pathogen!! Types of pathogen include bacteria, viruses, parasites, and fungi. These things can trigger your immune system immediately. Here is an explanation of all the pathogens:

Bacteria attack and digest tissue for themselves so they can have something to eat. Bacteria are scavengers, so they want to take as much as they can before the immune response destroys them. Bacterial diseases include strep throat, tetanus, Lyme disease and meningitis. Cavities are also just sugar-loving bacteria that eat away at your teeth. Viruses are a bit different. They invade cells and occupy them, so the virus gets all the nutrients they need to survive. They use the cell to multiply so when the cell dies each virus goes for another cell, multiplying even more. If a virus finds itself outside a warm cushy body, like on a door handle, it dies almost instantly because it doesn’t have any organisms to invade. Viral diseases include the chicken pox, Ebola, and HIV. Over 200 viruses are responsible for what we call the “common cold”. Parasites are also scavengers but are usually a little larger than bacteria. They feed on the tissue of the host organism and lay their eggs inside the bloodstream to reproduce. Protozoa are also Parasites, except they don’t lay eggs. Drinking dirty water is a common way to get a parasite infection. Common parasite infections include Giardia, tapeworm, hookworm and roundworm infections.
